To all whom it may concern:

Be it known that I, WILLIAM AMBLER, commission agent, a subject of the Queen of Great Britain and Ireland, residing at Bradford, Yorkshire, England, have invented certain Improvements in Apparatus for the Manufacture of Glass Bottles, (for which I and Jeremiah Rhodes, organist, and Samuel Rhodes, fine-art dealer, both subjects of the Queen of Great Britain and Ireland, and of Bradford, Yorkshire, England, have applied for and obtained Letters Patent in England, No. 6,639, dated May i, 1888; in Germany, No. 51,682, dated December 19,1888; in Austria-Hungary, No. 11,875 and No. 51,155, dated November 7, 1880; in Belgium, No. 81,318, dated December 17, 1888; in Canada, No. 30,546, dated January 14, 1889; in Sweden, No. 2,116, dated December 29, 1888, and in Norway, No. 1,310, dated December 26, 1888,) of which the following is a specification.

This invention relates to certain improvements in or applicable to the manufacture of glass bottles; and it consists, essentially, in means for molding molten glass by centrifugal agency caused to operate circumferentially around the axis of the bottle, preferably in a horizontal plane, and also endwise thereof in a plane at right angles to that of its first-referred-to movement of rotation, and for distributing the metal about the bottom, body, shoulder, and neck of the bottle into the required form of bottle in a correspondingly-formed mold adapted or combined with automatically opening and closing motions, allowing of the molten glass being inserted thereinto, of its being inclosed during the formation of the bottle, and of the formed bottle falling or being withdrawn therefrom, and with automatically-operatedmeans for rotating it about its axis for as long as may be required to distribute the molten glass (dropped into and onto the bottom of the mold while open and stationary) circumfertially and evenly within the same, so as also to form the side or body part and shoulder of the bottle, and also with automatically-operated means for simultaneously or during a portion 01' such time rotating it endwise of its axis or in a direction in which its axis will radiate in a plane at right angles to that of its movement of rotation around its axis, causing it to be carried round (while still rotating as aforesaid around its axis) for as long as may be required to distribute the metal into and around the neck of the mold, so as to form such part of the bottle, these motions or such of them as may be necessary being continued until the glass has sufficiently cooled, hardened, or set as to allow of the bot tle falling or being removed from the mold without liability of injury to its form, the molten glass inserted into the mold being thus caused by such combined motions imparted thereto to be distributed within all parts of the mold and to be formed into a bottle of the form thereof.

On the accompanying drawings, Figure 1 is a side elevation of an arrangement of apparatus embodying the said invention. Fig. 2 is a front elevation of part of such apparatus. Fig. 8 is an end View of means of imparting a differential speed of rotation to the moldin a horizontal plane. Fig. at is an end View of means of intermittently actuating the mold in a vertical plane.

at represents the mold, which is formed of cast-iron or other suitable metal in bottom and top parts 4 5, the former of which is cylindrical or of the required internal form and dimensions of those of the exterior of the body part and bottom of the bottle 6 and the latter of which is made in half parts of the required internal form and dimensions of those of the exterior of the shoulder and neck parts of the bottle, the mouth part of the bottle being also formed by such half parts 5 of the mold acting conjointly with a suitably-shaped removable plug 7, the operation of which is hereinafter described.

The parts 5 of the mold are hinged to the part a thereof, as at 8, and are also linked, as at 9, to a collar 10, surrounding the mold 1, and operated as hereinafter described, the operation thereof being effective in causing the parts 5 of the mold to be opened, as indicated by the dotted lines at a, when theneek of the mold occupies a downward direction to permit of the bottle falling thereout or being removed from the mold, and to continue open until the neck of the mold is caused to assume an upward direction, (rule the dotted lines at 1),) so as to permit of sufficient of the molten glass to form the desired bottle being inserted by the ladles, hereinafterdescribed, or in any other suitable manner into the mold onto the bottom thereof, immediately after which the mold is successively and automatically closed, clamped, rotated about its axis and also endwise thereof, as and as long as aforesaid, the neck of the mold again occupyin g a downward direction at the completion of the operation,and being then again opened to release the formed bottle, and so on.

The mold 4 is screwed on or otherwise firmly secured to a spindle 11, which is supported by a bracket 12, bolted, as at 13, to a carryingplate 14, projecting from or secured to a head 15, keyed on a tubular shaft 16, which is supported in bearings 17, bolted to the framing 18 of the machine,and is intermittently operated, as hereinafter described, for causing the rota tion of the mold in a vertical plane. The spindle 11 is also fitted with a friction-pulley 19, keyed thereon, and which is intermittently rotated in such a man n or as to cause the aforesaid rotation of the mold about its axis in a horizontal plane bya friction-disk 20, fast on a shaft 21 working within the shaft 16. The shaft 21 is differentially rotated from the motor-shaft 22 by means of a friction-wheel 23, keyed on the latter with facility of sliding endwise thereon, engaging with a friction-disk EZ-l, keyed on the shaft 21. The shaft 22 is supported in brackets 2'5, and is operated at the required speed by a belt passing round a pulley 26, fast thereon. The reciprocating endwise movement of the friction-wheel 23 along the shaft 22 is caused by means of a lever 59, (ride Fig. 3,) which is centered at 60 to the framing 1S and is formed with a fork 61, engaging with a clutch-groove (39, with which the hub of the wheel 23 is formed, thelever being rocked by a shaft 80, hereinafter referred to, by means of an eccentric-pin 63, projecting from a hub '64, keyed on such shaft.

The object of causing the mold to receive a differential speed of rotation is that while the body of the bottle is being formed when the molten glass has to be distributed over a greater area it may be more quickly rotated, and that when upon the mold being inverted part of the molten glass descends into the neck thereof, and while forming the neck of the bottle and while the mold is being kept rotating during the setting of the glass and completion of the formation of the bottle the mold may be more and more slowly rotated, as the continuation of the rotation is then only required to prevent the soft glass from collapsing.

The friction-wheel and disk 21 are intermittently put into and out of gear by means of a lever 27, centered at 28 and operated by a cam 29, keyed on the shaft 30, to which a continuous slow motion is imparted by a worm-wheel 31, keyed thereon and actuated by a worm 32 on a shaft 33,011 which is keyed a pulley 3%, which is actuated by a connecting-strap 35 from a pulley 31% on the shaft 22.

The shaft 16 is intermittently rotated (-comparatively slowly relatively to the speed of rotation of the mold around its axis) by means of a continuously-toothed wheel 37, keyed on the shaft 30, and an interruptedly-toothed wheel 38, keyed on the shaft 16, such wheels being respectively formed or fitted with a loeking-rim 39 and with one or more lockingplates 4:0. (l'z'dc Fig. 4-.) The locking-rim 39 is recessed at 95 to permit of the rotation of the locking-plates 40, when required, and is also formed with one or more projecting teeth t1, which as the wheel 37 rotates by striking the locking-plate 40 at the moment it is unlocked by the rim 39 causes the engagemci'it of the toothed portion of the wheel 38 with the toothed rim of the wheel 37, by which the shaft 10 is thus rotated until the following locking-plate 40 is locked by the rim 39. By the rotation thus imparted to the shaft 16 (to which, as aforesaid, the plate 14, carrying the mold, is made fast) the mold is reversed in position, which causes the molten glass to enter the neck thereof while still rotating about its axis and to form the neck of the bottle. As represented on the annexed drawings, the said locking-plates 40, rim 39, gearing 37 38, teeth l1, and recesses are so arranged as to impart one-half a revolution to the plate 1i and mold; but they maybe so arrangedas to give one and a half, two and a half, or more revolutions thereto. It is pre ferred, but not essential, that the mold should finish its rotation at the half of one or more revolutions, as the mold when pointing downward and when opened offers facilities forthe bottle falling into an appropriately-shaped and suitably-supported cup 66, (ride Fig. 1,) from which it is removed by an attendant to the annealing-kiln.

The aforesaid operations of opening and closing the mold to admit, respectively,of the molten glass being inserted into the mold while its open neck parts 5 are pointing up wardly, and of the formed bottle falling thereout or being removed therefrom while its open neck parts are pointing downwardly, and of inclosing the molten glass during the formation of the bottle are effected by means of the links 9 and collar 19, the latter of which is operated by a spur l2 on a sleeve 43, sliding on a rod 4.4, and is actuated in closing the jaws of the mold by a spring 45, bearing against a slide-bar 16, which carries the red at and slides on an extension of the plate 14. The movements of the slide-bar at are caused to be effected as the plate 1i is rotated about the axis of the shaft 16 by means of a pin -17, projecting from the bar at and engaging with a cam-groove 48 in a plate 50, and such movements are caused to be effective in clamping and releasing the jaws of the mold as and at the times required by means of an arm 51, carrying a clampingring 52, such arm being centered on a pin 53, carried by the slide-bar 4:6 and keyed to a pinion 54, which is caused to be partially rotated during the movement of the slide-piece by means of a racked slide-bar55, carried by the bar 16 and moved endwise by a pin 56 thereof entering a cam-slot 57 in a laterallyprojecting bracket 58. Lateral movement is by such means imparted to the clamping-rin g, in order that it may be removed laterally from above and from under the jaws when removed endwise away therefrom, so as to permit of free access to the mold when open, for the purposes aforesaid. Similar endwise and lateral movements are imparted to the plug 7, which is caused to be inserted into the neck of the mold immediately the clamping-ring has been lowered thereabou and to be removed therefrom immediately before the clampingring is removed, and such motions are effected by similar means, 46 47*, 48 51 53 541*, 55 56*, and 57*, to those hereinbefore described with reference to the clamping-ring. As the plug is lowered into the neck ofthe closed and clamped mold containing the molten glass it closes the aperture of the neck thereof. Its rotation around its axis then commences, the succeeding operations automatically following, as hereinbefore described.

69 represents a pawl carried by the cam plate 50 and engaging with a notch 7 O,formed on the rim 71 of a toothed wheel 68, which revolves around the shaft 16, and is driven from the shaft 30 by a toothed wheel 67, and 72 represents a like pawl carried by the head 15, fast on the shaft 16 and engaging with a notch 7 3, formed in the hub 74: of the plate 50, which also can revolve around the shaft 16. At the time, hereinbefore referred to, when the moldcarrying plate lel is actuated by the rotation of the shaft 16 the catch 72 causes the camplate 50 to be carried round the pawl 69, sliding over the rim 71 of the wheel 68. The plate 14 travels more quickly than the wheel 68. Consequently when the plate lahas completed its rotation the cam-plate 50 remains stationary until the pawl 69 is again engaged. Such an arrangement of apparatus may be duplicated to any required extent,in which case a series of molds and their necessary attachments may be arranged side by side and actuated by a (31111111011 cross-shaft, or two or more of the molds maybe arranged on one carryingplate, so that as one mold is filled and goes into operation the other rises empty and ready to go into operation.

At each operation of filling the mold the required amount of molten glass to form the intended bottle is ordinarily placed in the mold by means of ladles. The molten glass may, however, be placed in the mold by any other suitable means.
